[FLASH-USERS] Runtime error when trying to test Sod or Sedov

[Garishvili, Irakli]

Dear Flash Experts,

I am trying to test newest FLASH (3.3) version on a ³chaos_4_x86_64² linux
machine. 

I separately tried to built/run Sod and Sedov problems and I got pretty much
the same errors in both
cases. Setup and build (gmake) processes give me absolutely no trouble.
However, I get ³hdf5 I/O²-related runtime errors
 after executing Œmpirun ­np 1 flash3¹ command.

The strange thing is that runtime error messages totally change if I modify
³lrefine_max² (default was set to 6) value inside
 flash.par file. Below I copied last parts of 2 different error printouts I
get when running Sod problem.
First when lrefine_max = 6,  and second when lrefine_max = 3.

I also tested flash3 executable using valgrind which seemed to indicate some
memory leak issues.

I¹d really appreciate any suggestion on this matter.
Cheers,
Irakli.
